Appropriate layers were deposited onto the flexible polyimide substrates by spraying a suspension of nanocrystals followed by low-temperature annealing at $200^{circ}mathrm{C}$ for (10-120) min in Ar atm. The study of the samples by XRD and Raman spectroscopy showed that nanocrystals and CZTS thin films contain the kesterite phase with small impurities of CuxSnySz. Established that the chemical composition of the obtained films corresponds to the composition of the nanocrystals used for its application in solar cell development. Increasing the growth time of nanocrystals and annealing time of films causes an improvement in the crystalline quality of the main phase of the samples - kesterite. Showed that the CZTS thin films obtained by the presented method can be used as absorbers in third-generation solar cells.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"40 1","pages":"01NSSA12-1-01NSSA12-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86498261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The samples are based on adsorptive active anatase, the selective component is lithium-manganese spinel $mathrm{L}mathrm{i}mathrm{M}mathrm{n}_{2}mathrm{O}_{4}$. This component was synthesized preliminarily, its nanoparticles were inserted to the sol of insoluble titanium hydroxocomplexes, the nanocomposite was precipitated from this suspension and calcined at 500° C. A number of sorbents with different molar ratio of Ti:Mn was obtained by this manner, they were investigated by means of chemical analysis, X-ray diffraction, optical microscopy, TEM and SEM. The size of nanocrystallites is 20-30nm. Increasing the spinel amount has been found to decrease the sorbent grain size, however, they are mechanically durable due to $mathrm{T}mathrm{i}mathrm{O}_{2}$, which is a binder. Adsorption of $mathrm{L}mathrm{i}^{+}$ from the solution containing an excess of $mathrm{N}mathrm{a}^{+}$ ions was studied. The optimal amount of $mathrm{L}mathrm{i}mathrm{M}mathrm{n}_{2}mathrm{O}_{4}$ (13 %) has been found. The sample is obtained in a form of rather large grains $(approx 0.3 mathrm{~mm})$, the selectivity coefficient $mathrm{L}mathrm{i}^{+}/mathrm{N}mathrm{a}^{+}$ is about 500. The sorbent is regenerated with a 1 M HNO3 solution without manganese leakage. After 10 cycles of sorption-desorption, the concentrate was obtained, Further the concentrate can be used for $mathrm{L}mathrm{i}_{2}mathrm{C}mathrm{O}_{3}$ precipitation.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"1 1","pages":"02NEE02-1-02NEE02-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90327600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cross-linking of PAANa was verified by the absence of a C=C double bond by FTIR analysis. TGA of PAANa/PAPTMS hydrogels showed higher thermal stability compared to pure PAA hydrogel as well as the heat-resistance index (TiiRi) for PAANa/PAPTMS composites have greater values than additive ones. The hydrogels’ swelling capacity in distilled water is enhanced by 316% (from 16.81 to 70.06 g/g) at the incorporation of 10 wt% of PAPTMS. The mechanism of diffusion of hydrogels (except PAANa/PAPTMS = 80/20) has non-Fickian or anomalous character. The sorption curve of PAANa/PAPTMS = 80/20 sample has sigmoid character and was interpreted as a result of a combination of first-order kinetics and the overall autocatalytic process with its two rate constants.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"259 1","pages":"01NSSA02-1-01NSSA02-4"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77097790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The future of mechanical/electromechanical engineering lies in the design of smart materials and technologies. In this paper, the problem of material design in particular for applications in mechatronics industry and additive manufacturing-based production has been considered. Developed high-entropy alloys could outreach limited properties of conventionally used steels, ceramics and superalloys. The thermal and mechanical properties of refractory metals-based high-entropy alloys has been studied using a complex of analytical algorithms (linear, random forest and gradient boosting regression). The highest accuracy has been achieved by applying the gradient boosting model (above 91%). Performed calculations allowed to verify the properties of different alloys, hence simplify their further selection for the manufacturing. From the developed ranking of overall properties make the TiNbHfTaW, CrNbHfTaW and VNbHfTaW alloys demonstrated the best results for being used in applications for mechanical and electromechanical engineering.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"42 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81611469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
